Trek FX Plus 7S

Manufacturer: Trek

The Trek FX Plus 7S is a city-oriented electric bike built around a lightweight aluminum frame with clean lines, thanks to fully internal cable routing and an integrated in-frame battery that keeps the silhouette tidy. It targets riders who want a capable, connected commuter, complete with a dedicated smartphone app, a handlebar display, and both front and rear lights fitted as standard. The bike supports turbo and eco assist modes, giving riders straightforward control over how much help the motor provides on any given ride.

At the heart of the drivetrain sits a mid-drive motor rated at 300W with a maximum torque output of 50 Nm, paired with a 10-speed gearing system for fine-tuned cadence control across varied terrain. The 360 Wh removable battery charges in around three hours and supports a maximum range of approximately 63 km per charge, with an assisted top speed of 45 km/h. Stopping is handled by hydraulic disc brakes, and the bike weighs in at 18,650 g without front or rear suspension. There are no anti-theft features included in the specification.

Pros
  • The removable battery allows for convenient off-bike charging, adding practical flexibility for daily use
  • Internal cable routing keeps the frame looking clean and reduces exposure to dirt and wear
  • Both front and rear lights are built in, removing the need to add separate lighting for road visibility
  • A 10-speed drivetrain gives riders meaningful control over cadence across different gradients
  • Hydraulic disc brakes provide consistent stopping performance regardless of weather conditions
  • The dedicated smartphone app and onboard display offer a connected riding experience with accessible ride data
Cons
  • At 18,650 g, the bike is relatively heavy, which can make handling off the bike — such as carrying up stairs — more demanding
  • A maximum range of 63 km per charge may fall short for longer commutes or all-day use without access to charging
  • There are no anti-theft features included, so riders need to source separate security solutions
  • The lack of any suspension, front or rear, means the ride can feel firm on uneven or cobbled surfaces
Who is this for?

This bike is well-suited to adult commuters and urban riders who want a clean, connected daily ride. The mid-drive motor with turbo and eco modes makes it a practical choice for those navigating varied city terrain or moderate inclines, while the 10-speed drivetrain supports efficient pedalling across different gradients. Riders who value a tidy setup will appreciate the internal cable routing and integrated frame battery, and the inclusion of built-in lights, a display, and a dedicated smartphone app makes it a strong fit for tech-comfortable commuters seeking an all-in-one solution straight out of the box.

Who is this NOT for?

Riders looking to tackle rough trails or uneven off-road surfaces will find this bike limiting, as it offers no front or rear suspension, resulting in a firm ride on anything other than smooth pavement. The 63 km maximum range per charge may also fall short for users planning long-distance touring or full-day rides without reliable access to charging. Additionally, those who require built-in security will need to look elsewhere, as the bike carries no anti-theft features, making it less convenient for riders who regularly leave their bike unattended in public spaces.
